I disagree about the use of a strobe on a headlight. On a taillight it's great. On a headlight it's just annoying. Especially when over a few lumens. Headlights for bicycles are the only ones that strobe, and that's only because LED are easy to strobe and marketing hacks do it to add another "feature" to their product boxes.

Motorcycles and scooters riders have been being hit and killed for many years and none have ever strobed their headlights to reduce the risk. Why no strobe lights made for bikes before LED made it extremely easy, if there's such an important benefit? Because strobes are NOT a good idea for a headlight, from the viewer's perspective. And an SOS signal is NOT a strobe.
